Audio Networks
Pro16 A-Net input and output modules can be combined to create audio
networks of up to 64 audio channels with unlimited expansion.
8-Channel Systems
The most basic A-Net based system uses one input module connected
to one output module or Personal Mixer. For example, the AV-M8 can
be connected to an AV-P2 Output Module to deliver eight discrete line-
level audio signals to powered speakers, recording devices, mixers, etc.

A-Net, up to 500 feet
Connect A-Net Out on the AV-M8 to the A-Net In on any compatible
device. The eight audio channels from the AV-M8 appear as channels
1-8 on the output module.
16-Channel Systems
Any Pro16 input module can be substituted for the AV-M8 shown in
the diagram above. This includes the AN-16/i, AN-16/i-M, Y1 and D-16c
A-Net cards. These Pro16 devices provide 16 channels to the AV-P2.
Digital Splits
A-Net allows far more flexibility than just the simple configuration
outlined above. In fact, any number of Pro16 A-Net devices can be
connected to a single input module. This allows the creation of infinite
numbers of digital signal splits, with each additional A-Net device
capable of being located up to 500 feet (150 meters) away.
Splits can be used to send exact digital copies of the audio signals
from the input module to a live sound mixing console, a recording
system, an audio machine room, and a live television broadcast facility
simultaneously with no signal degradation. To add digital copies, or
“splits,” to a system, simply connect an A-Net Out to the A-Net In on
Pro16 output modules or Personal Mixers. The following diagram shows
one such system using a variety of Pro16 devices connected in series.

A-Net Out from the Pro16 input module connects to an A-Net
Distributor and then up to eight parallel streams can connect
additional Pro16 products.
The A-Net signal from the A-16D Distributor is connected to each A-Net
compatible device with a Cat-5e cable. Removing one A-Net device has
no effect on the other A-Net components being used.
P N ote : The A-16D Pro Distributor can also be used in this
configuration. It supplies DC power over the Cat-5e cable to
compatible Pro16 devices.
Extending A-Net Cable Runs
To span distances longer than the maximum specified for a single A-Net
cable (500 feet, 150 meters), the A-16D (or A-16D Pro) A-Net Distributor
can be used as a signal repeater. Simply insert the A-16D or A-16D Pro
into the A-Net stream at the 500-foot point and the A-Net signal will be
refreshed. Another 500 feet/150 meters of cable can then be added. This
process can be repeated as many times as required to extend cables. In
fact, any Pro16 device will refresh the A-Net signal and allow another
500-foot cable run between it and the next Pro16 device.
For long distance applications, fiber optic cable can be used to span
distances up to 50 miles (80 km) with the use of devices called media
converters. A media converter changes the Cat-5 Ethernet-based A-Net
signal to a fiber optical signal at the source location and then back to
Cat-5 at the destination. Several companies make media converters
that can be used with your Aviom equipment. Both single and multi-
mode fiber devices can be used. Refer to the Aviom website for a list of
approved devices.
